TYPICAL APPLICATION
DESCRIPTION
Hot Swap Controller with
I
2
C Compatible Monitoring
The LTC
?/DIV>
4280 Hot Swap" controller allows a board to be
safely inserted and removed from a live backplane. Using
an external N-channel pass transistor, board supply voltage
and inrush current are ramped up at an adjustable rate.
An I
2
C interface and onboard ADC allow for monitoring
of load current, voltage and fault status.
The device features adjustable analog foldback current
limit and a FILTER pin which con gures the time spent in
overcurrent before declaring a fault. An I
2
C interface may
con gure the part to latch off or automatically restart after
the LTC4280 detects a current limit fault.
The controller has additional features to interrupt the host
when a fault has occurred, notify when output power is
good, detect insertion of a load card, and power-up either
automatically upon insertion or wait for an I
2
C command
to turn on.
